Types of Mortgages in Norway: Variable, Fixed & Interest-Only

Variable Rate Mortgage (Flytende Rente)

Variable rate mortgages are the default choice for most Norwegian borrowers. The rate moves in line with Norges Bank's policy rate decisions, which are announced eight times per year. Banks must give 6 weeks' notice before passing a rate increase on to customers.

As of July 2026, the average effective variable rate for new mortgages at major Norwegian banks sits between 4.0% and 5.5%, depending on loan-to-value ratio, loan size and customer relationship. Borrowers with LTV below 60% typically access the most competitive rates.

Fixed Rate Mortgage (Fast Rente)

Fixed rate mortgages lock your interest rate for 3, 5 or occasionally 10 years. They are less common in Norway than in many European countries, partly because the variable market is well-established and partly because Norwegian consumers tend to tolerate rate volatility.

The main drawback is break costs (bruddgebyr): if you repay early, refinance or sell the property before the fixed period ends, you may owe the bank compensation equal to the difference in interest for the remaining period. Always model the break cost before choosing a fixed product.

Interest-Only Period (Avdragsfritt)

Some borrowers request an avdragsfritt period — typically at the start of a mortgage — during which only interest is paid and the principal is not reduced. This lowers the monthly payment but does not build equity. Finanstilsynet limits the availability of this option; banks assess each request individually based on the borrower's financial position.
